  1. Question 1

    Q1. What is the main reason for the splitting of spectral lines in the atomic emission spectrum?

    • A) The presence of a magnetic field
    • B) The presence of an electric field
    • C) The quantization of energy levels in the atom
    • D) The random motion of electrons

    Answer: The presence of a magnetic field

    Explanation: The main reason for the splitting of spectral lines in the atomic emission spectrum is the presence of a magnetic field, which causes the energy levels to become degenerate.
